TWIN SOCKET LAMP FIXTURE Filed May 29, 1950 I": mgr. 1 $2 INVENTOR 1 ATTORNEY I l atentecl et. 27, 1931 PATENT OFFICE LAURITZ'W. ANDERSEN, OF WATERBURY, CONNECTICUT TWIN SOCKET LAMP FIXTURE Application filed May 29,

' This invention relates to electric lamp fixtures, and more particularly to a shade support having a pair of depending clamping bands for resiliently embracing the opposed w sockets of a twin-lamp fixture to permit the shade to be readily rotated around the longitudinal axis of said fixture whenever desired.

One object of this invention is to provide 110 a shade support of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very efilcient and durable in use. F151 With these and other objects in view there has been illustrated on the accompanying drawings one form in which the invention mayv beconveniently embodied in practice.

In the drawings:

Fig. 1 represents a rear vertical sectional view of the shade, shade holder, and a twinlamp fixture upon which the shade holder is mounted.

Fig. 2 is a side sectional view of the same on a reduced scale, the section being taken along the line 22 of Fig. 1, looking in the direction of the arrows.

This application covers an improvement on the invention disclosed in my copending application for electric lamp shades, Serial No. 3d3,907, filed March 2, 1929.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral indicates a hollow supporting base having a two-wire electric conductor cord 11 extending through one side thereof for supplying current to a pair of lamps 12 and 13 located within a pair of threaded sockets 14 and 15, said sockets extending longitudinally in opposite directions from the body portion 16 of a twindamp fixture. The body portion 16 has a horizontal tube 17 extending laterally therefrom and said tube 17 is joined by a supporting tube 19 mounted on said base 10.

The cord 11 passes through the base 10, the vertical tube 19, and the horizontal tube 17 into the body portion 16 of the twin-lamp fixture, where it is connected by the usual flexible swivel connection 18 to a vertical 1930. Serial No. 456,961.

binding posts, not shown, to the center and shell terminals of the sockets 14 and 15. The body portion 16 is provided in its lower section with the usual switch-operating pullchain 20.

The shade support comprises a pair of resilient circular bands 21 and 22 shaped to fit about the sockets 1d and 15 respectively. Each of the bands 21 and 22 is provided with a pair of upwardly extending straight sections 23 and 24 having inwardly extending apertured ends 25 and 28, said apertures being adapt'edto be held in overlapping relation by a pair of headed screw bolts 27 and 28, respectively.

In order to connect the clampingbands 21 and 22 to an ornamental shade 35, provision is made of an elongated rectangular holding strip 29 having a depressed central section 30 and a pair of similar depressed aperturedend sections 31 and 32. The apertures of the outer depressed'sections'3l and 32 are shaped to fit over the depending ends of the bolts 27 and 28, mentionedabove. The central depressed section 30 is provided with an upwardly extending threaded stud 33 adapted to pass loosely through an aperture 34 in the lamp shade 35, said stud being adapted to receive an ornamental nut 36 for holding said shade rigidly in position. 30

As will be clear from Fig. 1, the ends of the holding strip 29 beyond the depressed sections 31 and 32 are bent upwardly at 37 and 38 into alinement with the strip 29 for forming a rigid support for the under surface of the shade 35. The heads 39 and 40 of the bolts 27 and 28 are adapted to be located Within a pair of raised sockets 4:1 and 42 formed in the top of the shade 35 adjacent the central stud 33. The shade 35 has a rear depending wall 13 provided with a vertical slot 44; adapted to embrace the lateral tube 17 to permit the shade to'be rotated about the longitudinal axis of the twin-socket fixture.

Operation ture, and. the oppositely disp sed: ends. 25 00 and 26 of said bands are brought into contact with each other. The holding strip 29 upon the stud 33,

will next be placed in the position shown with the depressed end sections 31 and 32 directly under the ends 25 and 26 of said bands, after I which the bolts'27 and 28 will be inserted downwardly through the apertures in said ends 25, 26, 31and 32.

The heads 39 and of said bolts will next be positioned within the sockets 4.1 and of the shade 35 withthe stud 33 extending up. through the aperture 34: of said shade. The ornamental nut 36 will then bescrewed down thus completing the as-' sembly of the device. 7

Onea-dvantage of the present invention is that all portions of the 1 shade-attaching means, except the ornamental nut '36,, are con cealed within the shade 35.

While there has been disclosed in this specification one form in which the'invention may be embodied, it is to be understoodthat this form isshown for the purpose of illustration only, and that the invention is not 1 to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short,

the invention includes all the 'modifications and embodiments coming within the scope of the following claims. I 9
